An oddity. The narrative, set in the well-known Earthsea setting, for the most part involves a domestic plot, wherein two has-beens take in a juvenile victim of sexual assault and handle the complexities of bucolic village life. The setting is supernatural, but the vast majority of the story is not. Sure, there's some supernaturalism hinted at and discussed, and one mythical creature from a prior installment makes an early appearance, and then shows up for the denouement. Other than that, this could've been written by Ibsen.
Some have complained that the feminist politics are too strident in this volume; those complainers are annoying. The gender politics are express, rather than implied--but they are fundamentally correct, and to disagree with them is to be outed irredeemably as philistine. Do they, however, ruin the book, as tendentious? Doubtful--else all books wherein a character makes political complaints are tendentious.
All that said, not sure if it's an entirely successful endeavor--though it is much more serious than the first three. Some perspective discipline problems, some pacing deficiencies maybe, somewhat too much time, perhaps, spent on the complexities of bucolic village life.
Recommended for secondhand pirates, abusers of the art, and she-kings.
